Is your feature request related to a problem? Please describe.

Describe the solution you'd like

Some add-ons allow you to modify application channel volumes individually.
Since the introduction of the "sound split" feature, NVDA systematically returns sound to both channels of applications to hear sound equally on both channels when "Disabled" mode is selected.
In this case, the modifications made by the add-ons are canceled

Describe alternatives you've considered

The "disabled" mode should mean that NVDA does nothing in this case and works as before the feature was introduced.

Additional context

This concerns alpha versions of NVDA.
